1、http基本命令

2、定位基本命令

参考文章：https://www.openedv.com/forum.php?mod=viewthread&tid=232045&page=1

 AT+CLBS=1,1

 +CLBS: 0,113.333941,23.308106,550

+CLBS: 0,113.333941,23.308106,550 //这就得到了想要的定位数据，这里直接输出的是经纬度。其中113.333941是经度，23.308106是纬度，

3、程序控制

 //SIM800C主测试程序 void sim800c_test(void) {  u8 key=0;   u8 timex=0;  u8 sim_ready=0; // u8 start_flag = 0;    POINT_COLOR=RED;  Show_Str_Mid(0,30,"ATK-SIM800C 测试程序",16,240); //LCD显示  while(sim800c_send_cmd("AT","OK",100))//检测是否应答AT指令   {   Show_Str(40,55,200,16,"未检测到模块!!!",16,0);   delay_ms(800);   LCD_Fill(40,55,200,55+16,WHITE);   Show_Str(40,55,200,16,"尝试连接模块...",16,0);   delay_ms(400);    }     LCD_Fill(40,55,200,55+16,WHITE);  key+=sim800c_send_cmd("ATE0","OK",200);//不回显  sim800c_mtest_ui(40,20);  ntp_update();//网络更新  while(1)  {   delay_ms(10);    sim_at_response(1);//检查GSM模块发送过来的数据,及时上传给电脑   if(sim_ready)//SIM卡就绪.   {    key=KEY_Scan(0);     if(key==KEY0_PRES)    { //     start_flag =!start_flag; //     if(start_flag) //     {               GPS_Location(); //定位测试       //     }      sim800c_mtest_ui(40,30);     timex=0;    }       }   if(timex==0)  //2.5秒左右更新一次   {    if(sim800c_gsminfo_show(40,225)==0)sim_ready=1;    else sim_ready=0;   }    if((timex%20)==0)LED0=!LED0;//200ms闪烁    timex++;    }   }  void GPS_Location() {   char *buf;   char *p,*p1,*p2;    char longitude[10],latitude[10];     buf=mymalloc(SRAMIN,80);//申请80个字节的内存   p=mymalloc(SRAMIN,50);//申请50个字节的内存   if(buf==NULL||p==NULL)   {     printf("buf=mymalloc 失败!!!!!!!!!!rn");      }      //查询经纬度信息    while(sim800c_send_cmd("AT+CLBS=1,1","+CLBS",200))   {      printf("查询经纬度失败rn");   } //+CLBS            p1=(u8*)strstr((const char*)USART3_RX_BUF,","); //第一个逗号开始         p2=(u8*)strstr((const char*)(p1+1),","); //第二个逗号开始    p2[0]=0;       sprintf((char*)longitude,"%s",p1+1); //经度      p1=(u8*)strstr((const char*)(p2+1),","); //第三个逗号开始    p1[0]=0;       sprintf((char*)latitude,"%s",p2+1); //纬度    USART3_RX_STA=0;            sprintf((char*)buf,"AT+HTTPPARA="URL","www.xiongyuchun.xyz:9999/Api/addDreamValueAPI.aspx?id=1&lng=%s&lat=%s"",longitude,latitude); //经纬度作为http请求参数   sim800c_send_cmd(buf,"OK",200);     sim800c_send_cmd("AT+HTTPACTION=0","OK",200);      printf("%srn",buf); //显示域名      myfree(SRAMIN,buf);   myfree(SRAMIN,p);      delay_ms(1000);   delay_ms(1000);   delay_ms(1000);    delay_ms(1000); //延时4s    }   //gprs网络初始化 void ntp_update(void) {     u8 ;     while(sim800c_send_cmd("AT+SAPBR=3,1,"Contype","GPRS"","OK",200))//配置承载场景1   {    printf("配置承载场景1失败rn");       }  while(sim800c_send_cmd("AT+SAPBR=3,1,"APN","CMNET"","OK",200))//设置为中国联通网络   {    printf("设置为中国联通网络失败rn");       }   while(sim800c_send_cmd("AT+SAPBR=1,1",0,200))//激活一个GPRS上下文   {    printf("激活一个GPRS上下文失败rn");       }       sim800c_send_cmd("AT+HTTPINIT","OK",200);              //http初始化   sim800c_send_cmd("AT+HTTPPARA="CID",1","OK",200);   //设置http回话参数     }
